ABSTRACT:
A thermal spray powder including cermet particles, each of which contains metal containing at least one selected from the group consisting of cobalt, chrome, and nickel, and tungsten carbide. The ratio of the summed weight of cermet particles having a particle size of 25 μm or more in the thermal spray powder with respect to the summed weight of the entire cermet particles in the thermal spray powder is 0.5 to 15%. A thermal spray coating formed from the thermal spray powder is suitable for the formation of a tungsten carbide-based cermet thermal spray coating for use in rolls such as corrugated rolls.
